Calculating Quarterly Averages From Daily Data

Jan 19, 2007

I have a sheet with daily data starting from 01/01/2000. I want to calculate daily averages for each quarter (i.e 2000Q1 value will be the average of values between 01/01/2000-31/03/2000, 2000Q2 will be average of values between 01/04/2000-31/06/2000, 2000Q3 average(01/07/2000-31/09/2000) and 2000Q4 will be the average of (01/10/2000-31/12/2000) etc. for all years afterwards.

I want to have the values in the corresponding cells starting with range ("e2")

The data was taken in 15 min intervals and is organized by date. I have one column with the date and time and another column with the data. I need to find the average for each day. I have almost a years worth of data. Is there any formula I can enter to find the values in a given day and return the average of the values (without having to select the data for each day)? I want to be able to copy the formula down a column with the value per day.

I need a formula that will provide monthly and quaterly averages from another worksheet, but only include the months that have occurred. I have the formula to obtain both the averages and quarter totals, but it is counting all months w/in the quarterly range before the months have occurred.

I have a spreadsheet that we are using as a Skills Matrix for the team. The area that the team member deals with is listed in Row 3. The scores for each person are recorded in Columns D to M. The process steps being scored against are in Rows 8 to 38, and are seperated by the area of responsibility.

I am trying to work out the average scores of each person depending on their area of responsibility. I can work out the totals easily enough using:

This is becuase it adds the 2 averages instead of working out the total average score. Is there an easy way around this?

i.e. For team members who have CM in Row 3 I need an average of certain cells, for team members who have V in Row 3 I need a different average and for those team members with both CM and V I need an overall average.

I have a database with monthly tabs and a summary sheet, on the summary sheet I calculate an average length of stay for each month (tab) but I need to find the yearly average and I don't know if there is a formula that would calculate the true average by using the monthly averages.

I want to be able to keep an average grade for my students through the course of a year. Work is marked with a grade A - U. I can use VLOOKUP to convert this to a numerical value but I can't work out how to generate an average from these numbers because every week there will be a new unit of work marked.

On the sample spreadsheet I have attached, the problem I have had is trying to get an average of the numerical values in row 7 because the cells without numbers have a VLOOKUP formula in them and mess up the calculation. And as the range of numbers will increase each time I mark a piece of work I can't use a fixed formula to find the average from say 10 numbers...

Below is my data point for each month. The goal I need to hit is 99%. So I need to figure out what minimum monthly percentage I need for the rest of the year, I will need to reach a goal of 99%, and if I can't reach it, return an error. Lastly, i want to be able next month to go in and fill in the AUG percentage with an absolute number (i.e. 89%) and then I would like the rest of the percentages to automatically update by figuring out the new minimum monthly average given the new value for August. I thought that I might be able to do that if there is a function that says "If cell is a number, leave it alone, if it's a formula, then include that cell in the calculation of the minimum monthly average.

I am currently using the following formula to calculate the average weekly demand of a product:

=SUM($G8:$CF8)/COUNTIF($G8:$CF8,">=0"))

It works fine, but sometimes the data I'm analysing doesn't span the full horizon (78 weeks). What I therefore want, is for the COUNTIF part to recognise the last populated Cell in the array, and to use the length of the array up to that point to calculate the average. Put another way, if I only have 52 weeks of data (the last populated Cell is $BF8), I want the COUNTIF to calculate based on 52 weeks and not 78 weeks.

Charter default premium is a calculated as a rate on outstanding charter hire.

Therefore if charter period is 1 year and daily hire is 20,000, outstanding charter hire (policy limit) at inception would be 20,000 x 365 = $7,300,000

However, by day 365 outstanding charter hire and prevailing policy limit would only be 20,000 x 1 day = $20,000

The premium is calculated on a daily pro rata basis on the reducing outstanding amounts.

I've calculated the premium on the attached spreadsheet assuming hire is monthly not daily, but it would be too laborious to try and calculate that for 12 months or more on a daily basis. What I'm hoping is that there's a formula, covering the range of data, presumably using the calculation on the first day and the last day, but which cuts out all the intermediate steps.

I'm trying to build a formula that allows me to see which item is the highest trending over a period of time I input.

I figured out the way how to select data between specific Start and End dates, but don't know how to interpret "trending" in a formula.

I was thinking maybe highest jump from beginning to end of interval, but what if it's a new item that was launched halfway through the interval and does poorly throughout, that would still be "trending" under that rationale....

how do i get excel to automate quarterly calculation? in column A1 I have Year and column B1 i have months (1-12) i have data in column D1 - H124 - I would like to run a macro where it will pick up Jan, Feb, march (1,2,3) for each year in column A and do a quarterly average right now i manually use =(D35*31+D36*28+D37*31)/90 but i would like to avoid human errors can i get excel to read if column B is 1,2, and 3 run quarterly average? and would excel know that in Feb there is only 28days except leap years?

Each quarter should have the bars standing next to each other, i.e. Q1 2013 should stand right beside Q1 2012. Between these pairs of quarter there should be a small space and the the next pair, Q2 2013 and Q2 2012, should be. So how do I do this?

When I use data without stacking several info in the same bar, this isnt a problem but when I have this "aaa, bbb,ccc,ddd" in every bar, this gets messed up.

I'm lookng for a way to add functionality across tabs in a spreadsheet where if you put a date and $ amount in different cells on an expense sheet, it recognizes the date of the amount input and it shows up in another tab with a list of monthly expenses.

I am currently trying to manipulate date ranges for monthly and quarterly reports, and am having trouble doing this. I have attached a file with an example of what I would essentially need.

I would need the "Nbr of Projects", "Nbr of Days worked", "Nbr of International Projects" and "Nbr of Local Projects" cells filled in under each respective report, based on the data in the top left.

If a project falls in two months, such as "18.12.2008 to 15.01.2009", this would be treated as 1 project for December and 1 project for January. Also, I would need only "NETWORKDAYS" included in the solution, so 11 days in this example.

I have data table with sales numbers by product, its wheel base, and over platform for months ranging from Aug 2013 - Nov 2013. This data table will populate with the complete month sales numbers after the month has finished going forward.

I have a table to the right of the listing the sum totals for each product (by wheel base and platform) by each quarter (rolling).

Now I need building a sumproduct average to calculate the quarterly average. This is not that simple because not all products (platform/wheel base) were available the entire quarter.

Also PLATFORM 3 in the tables are grouped - instead of listing platform 3a and platform 3b - using this in the formula:

(LEFT($D$2:$D$100,LEN($J9))=$J9)

Because not all products were available for the entire quarter - and the formula will need to count how many months that product, platform, wheel base was available during that quarter I'm guessing "=MOD(MONTH(A1)-1,3)+1" this may have to be used to count the number of months into the quarter the product was available.

How to form sub-totals quarterly in a typical list of transactions. Twist being it is not calendar year quarters but quarters from from 5 April to 5 July, 6July to 5 October etc. Typical table columns looks like:

I'm using a stacked bar chart (in Excel 2010, running on Windows 7) to create a simple Gantt-type chart - with just four or five bars. I've got my chart looking most of the way I want it to, but one thing still eludes me: I'd like to set up the major axis ticks to be quarters of the year (from 1/1/2011 to 4/1/2013). Since quarters are not regular intervals (they are not exactly every 90 days), I can't do this using Excel's standard functionality for choosing axis tick marks.

I am working on a spread sheet and am trying to use rolling averages of the last 3 months. I am using worksheets for each month with a final worksheet containing the 3 mo. rolling average. I tried using a formula with OFFSET and it worked fine if all the data was in 1 worksheet, but did not work for multiple worksheets averaging to another worksheet in the same workbook.

I am trying to work out the average volume of our daily downloads. I have used Vlookup to automate this. When there is no data it returns #N/A which is no problem. The problem arises when i try to work out the average for the month or peaks (MAX sum).

I have tried several variations of sumif/if/isna etc etc and am not having much luck. Below is an example of what i am trying to average out:#N/A620#N/A

That is 4 different days download data - I want it to ignore the 0's and #N/A and return the average for the days we actually had a download.

If I have a varying number of figures(say between 4 and 10) which I want the average of the first half of the set and an average of the second half, is there a function which I can use to calculate this? ie if there is 8 numbers in total then I need the average of the first four and last four... but if there is ten figures total then I need the average of the first five and last five.

I am inputing each day the total amount of sales. I am manually doing the averages for past 12 weeks on Monday sheet. I would like when I enter the amount for that week that the cells B84, C84, E84, F84 are automatically updated for the past 12 weeks. I have tried a few different approaches but I keep getting #ref or circular reference

We are trying to get an Average between 2 columns that have the same conditions. We have been using an array formula succesfully on data that is on 1 column and I have trying to incorporate an Offset into the formula with no luck.Here is our latetest attempt, WITHOUT THE OFFSET.The data is in Column P and Column N

I want a cell that takes each row in column B and subtracts column A from it... (10-5 for row 1). I want it to do that for all rows and then average that number. This would be easy if I were not using a pivot table with a lot of data.

How would I go about making a formula for that. The reason why I ask is because all the info I have seen refers to the cells with the averages need to be in sequence or range and nothing about the cells being seperated. I also tried using the countif method, but same prob, the cells need to be within a horizontal or vertical range
